When the data addresser is a system according to the determination result of the step S410, the data receiving server back interface 324 prevents the advertisement from being posted twice by determining it as an advertisement addition transmission finish checking message transmitted by the system and generating no additional advertisement.
When the data addresser is not a system according to the determination result of the step S410, the data receiving server back interface 324 provides data addressee information received from the data receiving server 140 to the user information analyzer 223 to request to inquire about the data addressee (S420).
The user information analyzer 223 requests the user information database 240 to inquire about the data addressee and receives a corresponding result. (S430, S440)
The user information analyzer 223 determines whether the data addressee is a permission user based on the inquiry result provided by the user information database 240. (S450)
When the data addressee is not a permission user according to the determination result of the step S450, the user information analyzer 223 notifies the data receiving server back interface 324 of the corresponding fact and no further process is undertaken.
When the data addressee is a permission user according to the determination result of the step S450, the user information analyzer 223 requests the user information database 240 to check the number of per day advertisement exposures of the data addressee. (S460, S470)
The user information analyzer 223 determines whether the number of per day advertisement exposures of the data addresser exceeds the per day exposure limit based on the number of per day advertisement exposures of the data addresser. (S480)
When the number of per day advertisement exposures of the data addressee exceeds the per day exposure limit according to the determination result of the step S480, the user information analyzer 223 notifies the data receiving server back interface 324 of the corresponding fact and no further process is undertaken.
When the number of per day advertisement exposures of the data addressee does not exceed the per day exposure limit according to the determination result of the step S480, the user information analyzer 223 inquires of the user information database 240 to acquire an advertisement category with the highest priority matched with the field of interests of which the data addressee is the most interested and a contents type selected by the data addressee when registering preference information. (S490, S500)
The user information analyzer 223 sets the current highest priority recorded in the user information database 240 to be the lowest one, and advances the priorities after the second priority by one to update the priority of the advertisement category with the next priority. (S510)
The user information analyzer 223 encodes data addressee information to issue a user ID. (S520)
The user information analyzer 223 transmits an advertisement category, a contents type, and a size to the advertisement information analyzer 224 to request the advertisement with the highest priority matched with the field of interests of which the data addressee is the most interested. (S530) The advertisement information analyzer 224 inquires of the advertisement information database 250 to acquire advertisement data with the highest priority appropriate for the data addressee, and provides the same to the user information analyzer 223. (S540, S550) In this instance, the advertisement data include contents, advertisement ID, sponsor, and user ID.

The data receiving server back interface 324 generates an advertisement by linking an advertisement ID and a user ID to the contents of the advertisement data. (S590)
The data receiving server back interface 324 requests the data provided by the data addresser who will add an advertisement from the data receiving server 140 of the network service medium. (S600) The data receiving server 140 transmits the data provided by the data addresser to the data receiving server back interface 324. (S610) In this instance, when transmitting service data to the data addressee, the data receiving server 140 provides a data ID received when storing the service data in the service data storage database 360. The data ID is generated and transmitted by the data structure analyze/generate device 340 when the network service medium stores the service data in the service data storage database.
As shown in FIG. 6, the data receiving server back interface 324 requests the data structure analyze/generate device 340 to generate new data that are generated by adding an advertisement to the original data received by the data addressee so that the new data may satisfy the data structure of the network service medium (S620). In this instance, the data structure analyze/generate device 340 finds the data designated by the service data storage database 360 and sets the same to be data to which an advertisement will be added in the case of a data ID. (S630, S640)
The data structure analyze/generate device 340 adds an advertisement to the data received by the addressee and provides them to the data receiving server back interface 324. (S650)
The data receiving server back interface 324 provides the advertisement-added new data generated by the data structure analyze/generate device 340 to the data receiving server 140 of the network service medium, and updates the number of per day advertisement exposures recorded in the user information database. (S670)

The data receiving server back interface 324 checks data transmitting server information used by the data transmitting user from the data transmitting server information database 262 through the user information analyzer 223, and determines whether the data transmitting server used by the data transmitting user is a cooperated medium. (S710, S720)
When the data transmitting server of the network service medium used by the data transmitting user is not a cooperated medium according to the determination result of the step S720, the data receiving server back interface 324 generates data to which advertisement information is added and transmits the data to the data transmitting user who is a permission user through the data transmitting server. (S730) In this instance, it is recommended to use the data transmitting server of the network service medium of the cooperated medium.
When the data transmitting server of the network service medium used by the data transmitting user is a cooperated medium according to the determination result of the step S720, no further process is undertaken.
FIG. 7 shows a method for linking the user's browser reading history and user preference information and always maintaining the latest user preference information according to an embodiment of the present invention.
The user registers his preference information through the user information register unit 221. (S10) In this instance, the user information register unit 221 encodes a mail address among user registration information and issues a user ID, and stores the issued user ID in the user's local environment. (S11) The user information register unit 221 stores the registered user preference information and the issued user ID in the user information database 240. (S12)
When the user is exposed on the advertisement on the sponsor's web (S13) or is connected to the cooperating user's web site (S15), the user information acquirer 122 preinstalled in the advertisement on the sponsor's web and the cooperating user's web site automatically collects the user ID stored in the user's local environment and the browser reading history and provides the browser reading history and the user ID to the user information analyzer 223. (S14, S16)
The user information analyzer 223 analyzes the browser reading history provided by the user information acquirer 122 to find the advertisement category of which the user is the most interested. (S17) In detail, the user information analyzer 223 extracts a keyword of the current page, accesses the web page having the URL corresponding to the previous page of the browser reading history to extract a keyword, and finds an advertisement category of which the user is interested from the keywords.
The user information analyzer 223 requests the user ID's preference information from the user information database 240 to receive user preference information corresponding to the user ID. (S19)
The user information analyzer 223 determines whether to update preference information based on the advertisement category acquired by analyzing the browser reading history and the user preference information stored in the user information database. (S20)
When it is not needed to update the preference information according to the determination result of the step S20, that is, when the advertisement category generated by analyzing the browser reading history does not correspond to the user preference information stored in the user information database, the analysis result of the browser reading history is ignored.
When it is needed to update the preference information according to the determination result of the step S20, that is, when the advertisement category generated by analyzing the browser reading history corresponds to the user preference information stored in the user information database, the advertisement category of the browser reading history analysis result is set to be higher than the priority of the user preference information. (S21) The current priority is advanced by one to update the priority of the advertisement category with the next priority. (S22)
According to the embodiment of the present invention, the user information analyzer 223 analyzes the information to be acquired from the browser reading history and processes the same as temporary user preference information, and sets the priority of the corresponding preference information to have a higher rank when the temporary user preference information acquired from the browser reading history matches the preference information that is registered in advance.
FIG. 8 and FIG. 9 show a process for updating the priority of advertisement categories satisfying changed preference information of the user and the priority of transmitted advertisements.
As shown in FIG. 8, as described above, the user information analyzer 223 analyzes the browser reading history acquired from the user information acquirer 122 and generates an advertisement category table of preference information on recent users. (S41)
The user information analyzer 223 acquires preference information of the user corresponding to the user ID acquired from the user information acquirer 122 from the user information database 240, filters items (horse riding and baseball in FIG. 9) of the advertisement category table that are not registered in the user information database 240 from among user preference information based on the browser reading history, and generates a new filtered advertisement category table. (S42)
The user information analyzer 223 considers the items of the filtered new advertisement category table as items of which the user is the most interested, and updates the existing priorities by sequentially ranking priorities of user preference information in the order of the filtered advertisement category table from the highest one to the lowest one. (S43)
As described with reference to FIG. 3 to FIG. 6, the user information analyzer 223 inquires the advertisement information analyzer 224 to request an advertisement (diet in FIG. 6) of the advertisement category having user preference information with the highest priority.
The advertisement information analyzer 224 selects the advertisement contents (“A Slim” in FIG. 9) having the highest transmission rank of the advertisement table corresponding to the advertisement category (diet) requested by the user information analyzer from among a plurality of advertisement tables stored in the advertisement information database 250, and provides the selected advertisement contents to the user information analyzer 223.
